"Specification of Letters Patent. Patented Aug. 13,1918.

Application filed October it, 1917. Serial at. 196,758.

To all whom it may concern:

Be it known that I, citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Spectacleaofwhich the following is a specification.

This invention relates to improvements 1n spectacles and more particularly in 'spectacles which are designed for the use of physicians and the like and has for its principal object to provide an improved and novel means for supporting the spectacles with respect to the person. Another ob ect of my invention is to provide an improved construction in spectacles whereby they may be supported from. the cranium and face with three different points of support. In spectacles as used by physicians and the like when performing an important operation it is important that they be held securely in place andthat they do not become loosened as is quite usual with. the usual type of nose mountings. The spectacle which is held by hooking over the cars is very annoying and quite objectionable to many people. My mounting is designed to obviate the above objections and to provide means whereby the glasses may be supported entirely by resting upon the nose and from gripping th cranium of the wearer.

Other objects will appear as my invention is more fully explained in the following specification, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a front elevation of my device shown in closed position.

Fig. 2 is an enlarged fragmentary end eleva tion of same with the holding means shown in open position. Fig. 3 is a plan of Fig. 2.

Referring more particularly to the drawing numeral 1 indicates the usual spectacle bows which are separated by a nose piece 2. My improvements includes relatively short clamp arms 3 which are hinged to levers l which in turn are secured by means of pivot pins 5 to the outer ends of bows 1. The levers 4: are provided with upturned thumb catches 4 on their free ends and are normally held in the position shown inFig. 1 by means of small coil springs 6. The object of the hinging together of the lever 4: and the Bonner J. James, a

clamp arm 3 is for the purpose of facilitating a neat and compact folding of the device and at the same time permitting the thumb catches to extend far enough away from the line of the bow in order to permit of the device being easily opened. The outer ends of the clamp arms 3 are provided with rounded and flattened grips 3 which are designed to grip the cranium without irritation. In using my device the levers and clamp arms are thrown outwardly with'the thumb and finger as is usual in nose piece glass mountings. The nose piece 2 is then placed upon the nose as usual andthe levers released with respect to the clamp arms engaging the cranium of the wearer about the point of the temple thereby gripping either side of. his head and securely holding the spectacles from dropping from the nose.

It will be understood that the clamp arms grip the sides of the head with sufficient force to prevent accidental removal and not hard enough to injure or annoy thewearer.

'While I have shown a particular form of embodiment of my. invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope'of the invention, and I therefore desire to avoid being limited to the exact form shown and described.

Having described my invention, what I claim as new and desire to protect by Letters Patent. is

1. In a device of the class described the combination of a pair of spectacle bows connected together by a nose piece, a pair of similar levers. pivot pins pivotally connecting the said levers intermediate their ends to the extreme ends of the said bows, clamp arms pivotally connected to the inner ends of the said levers and having a limited movement with respect thereto, coil springs wrapped around the said pivot pins and hooked over the outer ends of the said levers, whereby the levers and clamp arms are swung inwardly, lip-turned thumb catches on the outer ends of the said levers. whereby the levers and clamp arms may be moved without taking hold of the bows.

. 2." The combination with a pair of specta-' cle bows, of a pair of similar levers each pivoted midway its length to one end of the said bows, clamp arms pivotally connected levers, whereby the inner ends of the said to the nner ends of the sald levers and havlevers are normally thrown inwardly. 10 mg a llmlted movement with respect to the In testnnony whereof I afiix my signature c said levers, lip-turned thumb catches on the in the presence of two witnesses.

outer ends of the said levers, whereby the ROBT. J JAMES. levers and clamp arms may be actuated, and Witnesses:

coil springs mounted in the hinge point of FRANK H. FOWLER,

the levers and bows and hooked over the said MARGUERITE LEYDA.
